I used patterns from Cross Stitcher Magazine (issue no. 236, March 2011) and re-did them a bit. One of my contacts on Instagram, miss_smorgas, used these patterns to embroider her mobile cover, and she was sweet enough to tell me where she found the patterns. I downloaded the Cross Stitcher Magazine app to my iPad and downloaded the magazine in question, it cost 38 SEK (£2.99 / about 4 EUR).
